CONVEYER.

Application filed May 7,

To all whom it may concern:

Be it known that we, LEONARD E. House: and JAMES F. MILLER, citizens of the United States, and residents of Detroit, Wayne County, Michigan, have invented a new and Improved Conveyer, of which the following is a specification.

This invention relates to means for conveying boxes and other articles, but particularly the flasks employed in foundries, and its object is to provide a construction of this character which will slidably support the flasks and at the same time convey the sand which falls therefrom to a selected place.

This invention consists in a pair of tracks and a trough between them, a carriage slidable on the tracks, a driving chain attached to the carriage, and means including a conveyer flight extending down from the carriage into the trough and adapted to sweep along the sand or other material which may fall from the carriage into the trough.

It further consists in the details of construction illustrated in the accompanying drawing and particularly pointed out in the claims.

In the drawing, Fig. 1 is a side elevation of this improved conveyor with a portion of the carriage and of the trough broken away. Fig. 2 is a transverse section of the rails and trough and an end elevation of the carriage.

Similar reference characters refer to like parts throughout the several views.

The rails 1 shown in the drawing rest on the side frames 2 between which are the cross bars 3 which support the trough 4, preferably formed with a removable lining 5 which can be replaced when worn. The construction of the frames 2 and their number may be Varied as desired.

The carriage embodies a rectangular table or top 6 having a rim flange 7 if desired. The shoes 8 which slide on the rails 1 are shown provided with shanks 9 that extend into proper sockets 10 on the lower side of the top 6, the bolts 12 serving to hold the shoes in place. Two bosses 13 are shown extending down from the middle line of the top to receive the pins 14 on which the conveyer chain links 15 and 16 are mounted. The wheels and other driving mechanism for 1923. Serial No. 637,132.

this chain are not shown as it forms no part of this invention.

A connecting bar 17 is mounted on the lower ends of the pins 14 and a plate 18 ex tends down from this bar transversely to the tracks. Secured to the lower edge of this plate is a conveyer flight 19, preferably of leather, which sweeps up such sand or other material which falls from the table 6 into the trough and carries such material before it to an opening in the bottom of the trough, which opening is located at any convenient point.

The shoes 8 are preferably provided with guide flanges 20 to prevent the carriage from sliding laterally on the rails. These shoes as well as the flights 19 are easily replaced when worn. The central pull of the chain and its attachment to both the front and rear end of the carriage reduces the tendency of the table to swing, to a minimum.

The details of construction and the proportions of the parts may all be changed by those skilled in the art without departing from the spirit of our invention as set forth in the following claims Vi e claim 1. In a conveyor, the combination of a pair of rails, a carriage slidable thereon and embodying a rectangular top, a shoe below each corner of the top and resting on a rail, a pair of pins rigidly attached to and extending down from the middle line of the top, and a chain connecting to said pins which constitute the pintles on which the links of the chain are pivoted.

2. In a conveyer, the combination of a pair of rails, a trough between and below the rails, a carriage slidable on the rails and embodying a top and a pair of pins rigidly attached to and extending down from the middle line of the top, a chain connecting to said pins which constitute the pintles on which the links of the chain are pivoted, a bar connecting the lower ends of the pins below the chain, and a conveyor flight extending down from said bar into said trough.

3. In a conveyer, the combination of a carriage, rails to slidably support the carriage, a pair of pins rigidly attached to and extending from the carriage, and a conveyer chain connecting to said pins which constitute the pintles on which the links of the chain are pivoted.

4. In a conveyer, the combination of a pair of rails and a trough between them, a carriage slidable on the rails, a pair of pins which constitute the pintles on which the links of the chain are pivoted rigidly attached to and extending down from the carriage, a conveyer chain connecting to said pins, and a conveyer flight extending down below the chain into said trough.
